Bidirectional Programmable DC Power Supplies with Regenerative Load

 

When you need to both "source" and "sink" current, you NEED a Bidirectional power supply

The EA PSB Series programmable DC power supply is "bidirectional," meaning it has a built-in electronic load. The built-in load give the PSB the ability to "sink" current and provide energy recovery back to the source grid.  If you work with emobility applications or any industry requiring battery simulation or test, the EA bidirectional supply is a critical tool you need.

Regenerative Energy Recovery

Regenerative energy recovery cycleThe PSB is bidirectional, meaning it can source (provide) or sink (absorb) current and regenerate that current to the local power grid with up to 95% efficiency.. The energy efficiency saves electrical costs and runs cooler, making the PSB a very green solution on top of minimizing investment and test equipment space.

  • Save electricity + HVAC costs
  • Efficiency approximately 95%
  • Quick return on investment
  • Environmentally friendly

True Autoranging – Advantages for Test

autoranging-lp-finalAll EA power supplies provide true autoranging giving full power across a larger operating range to test more devices with just one supply. Autoranging enables the power supply to automatically adapt to higher output voltages when there is a smaller current or handle higher currents when there is a lower voltage. EA’s true autoranging can deliver full power down to 33% of rated output voltage, which is full power over a much wider range than any competing supply.

  • Save budget and space
  • No oversizing supply
  • One supply tests more
  • Versatile for future tests

Industry Leading High Power Density

EA PSB Series bidirectional DC power supplies feature industry leading power density. The PSB 9000 series packs up to 15 kW in a 3U chassis and the PSB 10000 series boasts up to 30 kW in a 4U chassis.

Output voltages range from 60V to 2000V DC with current specifications of 40A to 1000A. EA PSB power supplies can be easily paralleled providing up to 2 MW of power!

The PSB family of programmable dc power supplies come standard with an arbitrary waveform function generator, swappable digital interface control and built-in test routines for battery test, photovoltaic simulation and MPP tracking, to name a few.

All rackmount series of EA power supplies feature a 5" TFT Gorilla® Glass touch panel display for intuitive control, setup and programming. It will feel as familiar and easy to use as your smart phone!
